To all whom it may concern:

Be it known that I, WILLIAM M. MGNEILL, a citizen of the United States residing at Rosiclare, in the county of l-Iardin and State of Illinois, have invented certain new and useful Improvements in Scot-Blowers, of which the following is a specification.

This invention relates to new and useful improvements in soot blowers, and more particularly to soot blowers for boiler fur4 naces.

As is well known, boiler furnaces are generally supplied with Vrows of Vwater tubes, in which the water to be heated is` circulated. Scot, carried by the products of combustion, collects upon these tubes and has a tendency to insulate the tubes fromI the heat and consequently to lower the heat of the boiler. It has been the practice to supply the boiler with what is termed a false plete, which covers a number of openings in the lire wall of the Vcombustion chamber. Through these openings is introduced an open ended pipe of considerable length, connected with a source of compressed air supply, the purpose being to blow the soot from the tubes. This operation is exceedingly tedious and where a large battery of boilers is used, requires the undivided attention of at least one man.

In order to facilitate the operation of blowing the soot from the flues, I have provided in the `fire wall of the combustion chamber, a rotatable tubular member provided with a number of tubular arms, having openings therein. To the tubular member is introduced compressed air or steam which, passing out through the openings in the arms,Y operates to blow the soot from the tubes, means being providedwhereby the tubes may be oscillated within'the furnace. Means are also Aprovided to protect thetube from the action ofthe products of combustion. Y

Further objects will be obvious during the course ofthe following discussion.

In the drawings, whereinfor the purpose of illustration is shown a preferred; embodiment of my device. and in which like numerals are employed to designate like parts throughout the same, Y.

Fig. 6 is a perspective view showing my device in position in the boiler and' illustrating the application of the protecting tile and,

Fig. 7 is a plan view of my device.

Referring now more particularly to the drawings, the numeral 10 indicates the re wall of the combustion chamber of a furnace.

The fire wall 10 is provided with a vertical opening 11, in which is arranged a tubular member 12. The tubular member 12 is closed at its lower end and provided with a Yreduced extension 13,V which extends through an opening 14, formed in a casing 15.

Extension 13 is provided from one side thereof, with a rack 16 for a purpose hereinafter to appear. Upon the lower end of the extension 13 is mounted a miter gear 17. A shaft 18 is suitably journaled in the casing 15 and has secured thereto a miter gear 19, meshing with the gear 17. One end of the shaft 18 extends outside the casing, Iand is provided with'means 20 for rotating the same. Mounted upon the shaft 18 is a second shaft 21, having secured thereto a pinion 22 meshing with the rack 16 on the extension 13. The outer end of the shaft 21 is `provided with means for rotating the same, 23.

Surrounding the tubular member 12 adjacent to the upper end thereof is a sleeve 24, provided with radial arms 25` which are embedded in the lire wall. This sleeve positions the upper end of the tubular member. The Vextreme upper end of the tubular member is provided with an enlargement 26, formingthe male member of a bell slip joint. Mounted above the tubular member is an L 27, provided upon its upper end with a ltiene 28. The lower end of the L is expan ed either at right angles as shown in Fig. 1, or'downwardly tapered as shown in Fig. 4 to Vform the female member 29 of the having openings formed therein normally disposed within said pockets, means for shifting said tubes to bring them into alinement with the portions of said recesses communicating with the interior of the combustiton chamber, and means for oscillating said tu es.
